Along the past century, in many parts of the
world, for human and natural causes, forest
fires have become an increasing threat to
ambient and man. At the broadest scale, forest fires
interest researchers from very different areas, such as:
forestry, ecology, geography, physics and chemistry, mechanical
and chemical engineering, and applied mathematics. At a finer
forest fire physics can be considered mainly as a sub-area
of fire science, itself a part of combustion science, but
also important intersections with forestry
(fuels characterisation) and meteorology (interactions
between the fire and the atmosphere, at various
spatial and temporal scales). Within the different
phenomena that have been studied, the quasi-steady
propagation of surface forest fire fronts of
low-to-medium intensity is the most developed research subject
fire physics, which justifies the emphasis of the
workshop. Since the nineties, the two-sided challenge of constructing
models describing the behaviour of the fire front that
are, on the one hand, physically sound and general, and, on
the other hand, potentially applicable on operational grounds,
the proposal of a diversity of modelling strategies,
each one of them giving rise to some hard mathematical problems.
Such strategies are in different stages of
theoretical development and antagonize or
complement each other in a larger or lesser extent,
none of them self-imposing as clearly superior to the others.
of the lecturers precisely reflects the desire to encompass
the most relevant strategies that have been proposed.
The main goals of the event are:
- To promote the communication (i.e., mutual knowledge, criticisms,
possible future synergies respecting results and, above
all, strategies of research) among researchers with a common interest
and competence on theoretical modelling issues of forest fires,
with an emphasis on fire front propagation.
- To introduce to the Portuguese mathematicians the open mathematical
and physical research problems brought up by some representative
theoretical modelling strategies that are being used
to describe the behaviour of forest fire fronts.
